Depto de Biodiversidad y Biología Evolutiva, Museo Nacional de Ciencias Naturales (C.S.I.C.), José Gutienez Abascal 2,28006 Madrid, Espagne Abstract. - Results of a survey on weevil fauna of the xerothermic area of Los Monegros are reported. A total of 105 species of Curculionoidea of the families Urodontidae, Auelabidae, Apionidae, Rhynchophoridae and Curculionidae were found. Two new species are described: Ceutorhynchus gtpsophilus Colonnelli, n. sp., and Strophosoma (Neliocarus) monegrense Pelletier, n. sp. Broconius professas (Faust, 1885) is newly recorded from Europe, as well as the genus Broconius Desbrochers, 1904. Baris corsicana Schultze, 1904 is a new record for the Spanish fauna. Ecological data are provided for most of the species, including the possible host plants. Zoogeographical analysis revealed that most species have a Mediterranean distribution, and that 1206 of them are Spanish endemics. A small number of weevils show a disjunct distribution with populations in arid sites of both Spain and the eastern Mediterranean (or westem Asia). Other species have their closest relatives in the eastern Mediterranean. The high faunistic diversity and the presence of endemics make necessary to protect this site to ensure the continuity of Los Monegros steppe habitat. Résumé. - Les résultats d'une étude sur la faune des Curculionides de I'aire xérothermique des Monegros sont rapportés. Un total de 105 espéces de Curculionoidea des familles Urodontidae, Attelabidae, Apionidae, Rhynchophoridae et Curculionidae a été trouvé. Deux nouvelles espéces sont décrites: Ceutorhynchus g,tpsophilus Colonnelli, n. sp. et Strophosoma (Neliocarus) manegrense Pelletier, n. sp. Broconius professus (Faust, 1885) et le genre Broconius Desbrochers , 1904 lui-méme sont mentionnés pour la premiére fois en Europe. Baris corsicana Schultze, 1904 est nouveau pour la faune espagnole. Des données d'écologie, incluant les plantes-hótes possibles, sont indiquées pour la plupart des espéces. Une analyse zoogéographique indique que la majorité des espéces ont une distribution méditerranéenne et que l2o/o sont endémiques de I'Espagne. Un petit nombre de Curculionides présente une distribution disjointe avec des populations de sites arides d'Espagne ou de Méditerranée orientale (ou d'Asie occidentale). D'autres espéces ont leurs plus proches parents dans la région méditerranéenne orientale. Le haut degré de diversité et la présence d'endémiques rend nécessaire la protection de ce site afin de permettre le maintien de I'habitat steppique des Monegros.

The weevil fauna of Spain is very poorly known if compared with that of other countries of Europe. Volumes concerning Curculionoidea of the main work on Spanish fauna, the so- called "Fauna lbérica" monographs still await publication, so the only catalogue of weevils from Spain is that published by IcLEsns (1922). At present, there are only isolate studies on Curculionoidea from some areas (Courrn, 1981, MoRoogR,1921,1924, RouDmn, 1954, YsrAzevnzDp Casrno & Menrñ,Lggz,YptÁzevpzDs Cesrno et a1.,1990, SANZ, 1994, this last survey probably the most complete). No investigations have been made on the weevil fauna of north-east Spain, despite this area holds interesting zones, among them the arid site known as Los Monegros (fig. l). However, a comprehensive study of fauna and flora of Los 4OZ VelÁzqunz D¡ CRsrpo et al. - Curculionides du nord-est de l'Espagne Monegros was carried out from 1989 to 1998 by the second author, mainly in the locality Retuerta de Pina, near to the city Pina de Ebro. The purpose of this study was to elucidate the state of the biodiversity of this site, in view of a possible protection of the zone. A huge number of invertebrate specimens were collected, which includes, so far, more than 5400 species (Bresco-ZuMETA & MeLIc, 1999 :36). Many scientists who studied the specimens collected supported this survey; some of their results were published in the last decade, including the description of 107 new species of insects. Among Coleoptera, data on Melyridae (CoNsraNrnr,l99l), Scarabaeoidea (LórEz CoróN & Brasco-Zu\'nrA,1997), Rhipiphoridae (LóvnzColóN et al.,1997),and aquatic beetles (RnEna et a1.,1996) have been published. As far as Curculionoidea are concemed, only the description of some new species (Strophosoma blascoi Pelletier, 1996, Trachyphloeus crassicornís Borovec, 1996, Aspídiotes gonzalezi Sánchez-Ruiz & Alonso-Zarazaga, 1994) and a brief communication (VelÁzquEz DE CasrRo & Br¡.sco-Zuvtnrt, 1994:189) have been published. This is thus a complete report on the whole of Curculionoidea (Scolytidae and Platypodidae excepted), one of the groups which shows the greatest diversity within Coleoptera. TH¡ sruoy AREA Los Monegros is a geographical region placed in the middle of the Ebro valley (including part of Huesca and Zaragozaprovinces, fig. l). The general climate is Meditenanean, although more continental and arid than usual, due to the isolating effects of the surrounding mountain ranges. The usual annual temperature range is more than 50o (from -10oC to more than 40'C) with possibility of frost for up to seven months a yeú (Ocuoe, 1982). Annual precipitation in the area ranges from 200 to 400 mm. Winds are predominantly dry. These climatic conditions allow the growth of a climax vegetation of Juniperus thurifera L. forest, which belongs to the plant association Junipeietum phoeníceo-thuriferae (Br.-Bl. & O. Bolós) Rivas-Martínez (Rtvns-ManrñYz, 1987). Due to anthropic factors, however, this community has disappeared from most part of the region. The best conserved forests remain in a 20 km2 area in a site known as "Retuerta de Pina", which belongs to the municipality of Pina de Ebro (Zaragoza province), with the uru grid reference 30TYL29. This was the sampling site for the present study. The main lithological element is the miocenic "Retuerta formation" (QunaNrES, 1978), with massive white or very light gypsum soils and gypsiferous slimes. Altitudes range from 300 to 400 m above sea level. Vegetation consists in cleared forests, in which the composition of the undergrowth is determined by changes in orientation and soil composition. Typical communities are as follows (Bnerix- Br.aNeur,r & BoLos, 1957, OcHoe, 1982). l. Lygeo sparti-Stipetum lagascae Br.-Bl. & O. Bolós and Agropyro cristati-Lygeetum spartiBr.- Bl. & O. Bolós. Both are very similar steppe graminaceous communities, with Stipa spp., Lygeum spartumL. and Agropyron cristatum (L.) Gaertner, all growing in deep soils. Samples collected in both associations are grouped with the narne Agropyro-Lygeion. 2. Helianthemetum squamati Br.-Bl. & O. Bolós. Strongly cleared shrubs growing on very thin gypseous soils in sunny places. Typical plants are Helianthemum squamatum (L.) Pers., Herniaria fruticosa L. and Launaea pttmila (Cav.) O. Kuntze. 3. Ononidetum tridentatae Br.-Bl. & O. Bolós. Dense shrubs growing on deep gypsaceous soils, with Ononis tridentata L., Helianthemum lavandulifulium Miller, Gypsophila struthium subsp. hí sp ani c a (Willk. ) G.L ópez, and Ro s mar inus ffi c i nal i s L. 4. Salsolo vermiculatae-Artemisietum herba-albae Br.-Bl. & O. Bolós and Salsolo vermiculatae- Peganetum harmalae Br.-Bl. & O. Bolós. Niftophilous communities found on abandoned fields and in places with organic denitus (mostly from sheep and rabbits). Typical plants are Salsola vermiculata L., Peganum harmalaL. and Artemisia herba-aláa Asso.

Halophilous community with Suaeda vera J.F. Gmelin, Atriplex halímus L. and Tamarix canariensis Willd., growing in abandoned saline fields. 6. Onopordetum nervosi Br.-Bl. & O. Bolós. Nitrophilous community found in abandoned fields or in places with organic detritus (mostly of vegetal origin), with Onopordum corymbosum Willk. and O. nervosum Boiss. 7.
